The Anker Laptop Power Bank (25K, 165W, Built-In and Retractable Cables) is a high-capacity portable charger designed to meet the demands of modern devices, including laptops, smartphones, and tablets. With its substantial 25,000mAh capacity and versatile charging options, it aims to provide users with reliable power on the go.
Design and Build Quality
Measuring 15.7 x 5.41 x 4.9 cm and weighing approximately 594 grams, the power bank is relatively compact given its high capacity, though it is on the heavier side compared to standard power banks. This heft is a trade-off for the extended power it offers. The device features a sleek, minimalist design with a matte finish that resists fingerprints. One of its standout features is the inclusion of two built-in USB-C cables: an 8.6-inch cable that doubles as a carrying strap and a 27.2-inch retractable cable. These integrated cables enhance portability and ensure that users always have the necessary connections without carrying extra cords.
Charging Capabilities
Equipped with three USB-C ports and one USB-A port, the power bank offers versatile charging options:
Triple 100W USB-C Ports: Each USB-C port can deliver up to 100W of power, allowing for fast charging of laptops, tablets, and smartphones. For instance, it can charge a 16-inch MacBook Pro (M3) to 50% in approximately 33 minutes.
USB-A Port: The USB-A port provides up to 33W of power, suitable for charging devices like smartphones and earbuds.
The power bank supports simultaneous charging of up to four devices, with a maximum combined output of 165W when two devices are connected and 130W when three or four devices are connected. This makes it a versatile solution for users with multiple devices
Battery Capacity and Performance
With a 25,000mAh capacity, the power bank can provide multiple charges for various devices:
Smartphones: It can charge an iPhone 16 to 50% in about 25 minutes. Based on typical smartphone battery capacities, users can expect approximately 4 to 5 full charges.
Laptops: The high capacity and 100W output per USB-C port make it suitable for charging laptops, providing at least one full charge for most models.
It's important to note that, due to energy loss during charging, the actual usable capacity is around 65% of the total, translating to approximately 16,250mAh.
Display and User Interface
The power bank features a high-resolution smart display that provides real-time information, including remaining battery percentage, current output and input, and estimated recharge times. This allows users to monitor the charging status and manage power distribution effectively.
Safety Features
Anker has incorporated its proprietary ActiveShield 2.0 technology, which monitors temperature over 3 million times per day to ensure safe charging. This continuous protection helps prevent overheating and safeguards connected devices.
Portability and Convenience
While the power bank's weight of 594 grams makes it less portable than smaller models, the integrated cables add a layer of convenience by eliminating the need to carry separate cords. However, users should consider the weight if they plan to carry it in a bag or pocket regularly.
Recharging the Power Bank
The power bank supports fast recharging, with each USB-C port capable of accepting up to 100W input. Using a 100W charger at room temperature (25°C), it can recharge to 30% capacity in just 20 minutes and fully recharge in approximately 2 hours.
